Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    System.setProperty("java.net.useSystemProxies", "true");
    List l = ProxySelector.getDefault().select(new URI("http://www.yahoo.com/"));

    for (Iterator iter = l.iterator(); iter.hasNext();) {
        Proxy proxy = (Proxy) iter.next();
        System.out.println("proxy hostname : " + proxy.type());
        InetSocketAddress addr = (InetSocketAddress) proxy.address();
        if (addr == null) {
            System.out.println("No Proxy");
        } else {//from w w  w . java  2 s.  c o  m
            System.out.println("proxy hostname : " + addr.getHostName());
            System.out.println("proxy port : " + addr.getPort());
